Sony TA-N77ES Amplifier
The Sony TA-N77ES is Japan’s greatest power amplifier of all time. The TA-N77ES was Sony’s last effort at pushing the envelope of serious power amplifiers at the end of HI-FI’s glory days.
These are nearly impossible to find at any price, especially with meter lights that actually work, because they were so insanely expensive when new that few people could afford to buy them. The Sony TA-N77ES is Japan's greatest power amplifier of all time. It's a 55-pound behemoth with huge meters that sounds and measures extremely well.
Sony cleverly sold the design to Accuphase in 1989, who still sells it today in their model P-4100. The Accuphase P-4100 uses the same isolated power supply for the drivers ("Spontaneous Twin Drive"), the same triple-parallel bipolar output stage, the same idle-power draw, and even the same speaker, meter, input and attenuator controls — and of course the same wonderful huge meters. Accuphase reduced the P-4100's output power for economic reasons to only 90 WPC, and of course raised the price by ten times over what Sony asked for this landmark TA-N77ES.
